The preferred forms of invention

See also accompanying drawing below, in different accompanying drawings, use identical label to represent same or analogous member.

Fig. 1 is the exploded perspective view of structure of the toy car of expression master embodiment of the present invention.Fig. 2 is the side sectional view of Fig. 1 toy car.As shown in the figure, the toy car 100 of master embodiment of the present invention comprises a body 10, has forward and backward

wheel shaft

20 and 30 to pass across body 10 in the forward and backward position of body 10.The two ends of front axle 20 are equipped with two front-wheels, and the two ends of hind axle 30 are equipped with two trailing wheels simultaneously.Front and rear wheel respectively has a

wheel rim

50 or 60, and each fixed cover is provided with a

permanent magnet ring

55 or 65 on the forward and backward wheel rim 50 or 60.In the present invention,

permanent magnet ring

55 and 65 has high magnetic force, and toy car 100 can be moved along a magnetic orbit or on a metallic walls, and its wheel closely contacts with this track or wall simultaneously.

As shown in the figure, be provided with a plurality of gears in the body 10 of toy car 100, they form a driving force holding device of toy car 100 in the mode that is same as traditional unpowered toy car.That is to say, at middle body each sheathed one

first gear

22 or 32 on forward and backward wheel shaft 20 and 30.Body 10 usefulness axles rotatably is equipped with one

first pinion

24 or 34, they with two

first gears

22 and 32 in a relevant engagement.

First pinion

24 and 34 respectively is combined into one coaxially with a second

largest gear

26 or 36, thereby can therewith rotate.There is the relative position of one second pinion 42 on its diametric(al) to mesh with these two second

largest gears

26 and 36 simultaneously.This second pinion 42 and a flywheel 40 are combined into one coaxially, and are loaded on body 10 and can rotate with two second

largest gears

26 and 36 with axle.

In above-mentioned toy car 100, between front and rear wheel by being formed centrally a V-shaped groove 15 in body 10 bottoms.

Fig. 3 is the view that presentation graphs 1 toy car 100 moves along a metal track 2 that vertically coils.

For toy car 100 is moved on track 2, with hand with toy car 100 after moving forward several times repeatedly on the bearing-surface, earlier toy car 100 is placed on an initial position " A " specified on the horizontal component of metal track 2.When on the original position that as mentioned above toy car 100 is placed on metal track 2, the wheel of toy car 100 rotates because of inertia force, and this mode with the traditional toy car is identical.In this case, the revolving force of wheel is pressed the sequence delivery of

first gear

22 and 32,

first pinion

24 and 34, second

largest gear

26 and 36 and second pinion 42 to flywheel 40 by transmission device, thereby flywheel 40 is rotated.Along with heavier flywheel 40 rotates as mentioned above, the momentum of flywheel by transmission device by second pinion 42, second

largest gear

26 and 36,

first pinion

24 and 34 and the sequence delivery of

first gear

22 and 32 to forward and backward

wheel shaft

20 and 30, reach one section preset time thereby rotate front and rear wheel continuously with basic rotating speed uniformly.Therefore, " move and arrive a final position " G " on another horizontal component of track 2 along track 2, simultaneously by way of position B, C, D, E and F by A " from the position for toy car 100.When toy car 100 as mentioned above when track 2 moves, there is the toy car 100 of

magnet ring

55 and 65 to be attached to metal track 2 continuously on its wheel, even toy car 100 on the coiling of track 2 part when mobile (turn upside down, be positioned at position " D " and " E " of coiling part) can not de-orbit 2 yet.

In the present invention, owing to each wheel is covered by a

magnet ring

55 or 65 on its periphery fully, thereby the magnetic attraction between wheel and the track 2 can be disturbed toy car 100 needed smooth and easy moving on metal track 2.But, can improve the momentum of flywheel 40, the driving force of toy car 100 is increased, overcome this magnetic attraction effectively by increasing the weight of flywheel 40.

That is to say that when toy car 100 was mobile on track 2, front and rear wheel tangentially contacted in the end face of track 2 continuously.In this case, the magnetic attraction that is produced in the rear of the tangential contact wire of wheel part between each wheel and the track 2 attempts to make toy car 100 to move backward.On the other hand, the magnetic attraction that produces at the front part branch of the tangential contact wire of wheel between each wheel and the track 2 attempts to make toy car 100 to move forward.Like this, these two kinds of magnetic attraction are repealed by implication, thereby almost completely can not disturb toy car 100 moving on track 2.Therefore, as can be seen, have only the magnetic attraction that results from tangential contact wire place between each wheel and the track 2 just can in the moving process of toy car 100, attempt to stop toy car 100 on the track 2.Yet because the tangential contact wire of wheel only forms very little area, thereby the magnetic attraction that results from tangential contact wire place between wheel and the track 2 almost is negligible.Therefore, when improving the toy car driving force when increasing flywheel 40 weight, toy car 100 can move along metal track 2 swimmingly, and unlikely is subjected to the interference of the magnetic attraction between wheel and

magnetic rings

55 and 65.

Fig. 4 a and 4b are the cutaway views of cross section of metal track 2 of the different modification of expression master embodiment of the present invention.In the track 2 of Fig. 4 a, lay a longitudinal metal bar 2a at the end face upper edge of track 2d central axis, its width equals the distance between the felly.In the track 2 of Fig. 4 b, lay two longitudinal metal bar 2c abreast along the end face of track 2d, their the width all width with each wheel is identical.When using the track 2 of Fig. 4 a or 4b, for the wheel that is covered with

permanent magnet ring

55 or 65 on the periphery, at toy car 100 along preventing its accident de-orbit 2 bonding jumper 2a or 2c in the moving process of track 2 substantially fully.Therefore, toy car 100 can stably move along track 2, and the 2d that can accident do not de-orbit.

Fig. 5 is the view that presentation graphs 1 toy car 100 moves on a vertical metallic walls.

For toy car 100 is moved on this vertical metallic walls, with hand with toy car 100 after moving forward several times repeatedly on the bearing-surface, earlier toy car 100 is placed on an initial position " L " specified on the horizontal plane.When on the original position that as mentioned above toy car 100 is placed on metal track 2, the wheel of toy car 100 rotates because of inertia force.In this case, the revolving force of wheel is passed to flywheel 40 to be same as the described mode of Fig. 3.Along with heavier flywheel 40 rotates, the momentum of flywheel 40 is passed to forward and backward

wheel shaft

20 and 30 by transmission device, reaches one section preset time thereby rotate front and rear wheel continuously with basic rotating speed uniformly.Therefore, " L ", arrive the position " M " at vertical wall base angle to toy car 100, and move up along vertical wall from the position.In this case, owing to the

magnetic rings

55 and 65 that is sheathed on the wheel, toy car 100 can move up along vertical wall, and can not slide from wall.

When toy car 100 moved on wall as mentioned above, toy car 100 was at the drift angle " P " of " O " back arrival wall by way of the centre position.In this case, after the drift angle " P " by wall was on drift angle " P " horizontal component on every side fully at front-wheel, drift angle " P " was contained in the V-shaped groove 15 of body 10.Like this, toy car 100 can be crossed drift angle " P " swimmingly and arrive position " Q " on the horizontal plane.Because toy car 100 moves up swimmingly and crosses can ascend swimmingly all steps of ladder of the drift angle " P " of wall thereby toy car 100 along vertical wall as mentioned above.

In toy car 100 of the present invention, can a sheathed rubber packing 55a or a 65a on the

permanent magnet ring

55 or 65 of each wheel, improving the walking stability of toy car 100, and prevent that wheel from producing undesirable skidding from the teeth outwards.Rubber packing 55a and 65a can prevent that also toy car 100 from damaging or break when bumping against hard structure.In this case, preferably make rubber packing 55a and 65a thin as much as possible, so that permanent magnet ring 55 that causes because of rubber packing 55a and 65a and 65 magnetic force reduce to reach bottom line.

Fig. 6 is the stereogram of the toy car of second embodiment of the invention.As shown in the figure, the toy car 200 of this second embodiment has a crawler belt 70, and this crawler belt is walked around each front-wheel and corresponding trailing wheel in the mode of the crawler belt that is same as traditional military tank or tractor, and the revolving force of two wheels is incorporated into together.In this second embodiment, each front and rear wheel of toy car 200 on its periphery to be same as the described mode of main embodiment closely coated with a

permanent magnet ring

55 or 65.

When the toy car 200 with two crawler belts that are oppositely arranged 70 was mobile on the step of a ladder, crawler belt 70 closely contacted with the drift angle of each step all the time, thereby toy car 200 can be more smooth and easy and climb all steps of about ladder effectively.

Fig. 7 is the side sectional view of the toy car of third embodiment of the invention.In the toy car 300 of the 3rd embodiment, a float 80 is set, on the bottom of body 10 so that allow body 10 fly on the water surface.The toy car 300 of this embodiment also has water wheels 90 on each front and rear wheel.When current, trailing wheel rotated, these water wheels 90 were pushed ahead toy car 300 waterpower.

Each water wheels 90 is formed by a plurality of blades 95, and these blades are arranged on the sidewall of each front and rear wheel of toy car 300 regularly.Above-mentioned blade 95 turns forward separately, thus current, when trailing wheel rotates on the water these blades with water to pusher.When the toy car 100 of this embodiment was that metal track 2 or other surface enter in the immobilising water when upward moving, body 10 flew on the water surface because of its float 80 major parts.In addition, because the momentum of flywheel 40, the blade of water wheels 90 95 rotates with front and rear wheel, thus with water to pusher.Therefore, toy car 300 can move forward on the water surface by the revolving force of wheel, and by float 80 body 10 is flown on the water surface.

In the toy car 100,200 or 300 of master embodiment to the three embodiment of the present invention, the sheathed one

permanent magnet ring

55 or 65 with predetermined thickness on the wheel rim of each front and rear wheel, move so that toy car can be stablized on the surface of multiple magnetic texure, and can not break away from these structures are unexpected.Yet, be understood that toy car of the present invention is not limited to above-mentioned structure, and can freely change to a certain extent, and is so that move along different tracks, as will be described below between two or more parts.

Fig. 8 is fourth embodiment of the invention, be designed to the stereogram of the toy car 400 that can be between two or more parts moves along different tracks.

In the fourth embodiment of the present invention, toy car 400 has a plurality of main road wheels 115, is provided with a driven unit 120 in the body 110 of toy car 400 and is used to drive wheel 115.Above-mentioned driven unit 120 is operated together by one or more driven wheel 125 collaborative wheels 115.

In the toy car 400 of this embodiment, main road wheel 115 comprises the front and rear wheel that is arranged on the front and rear portions office on body 110 bottoms.When needs drive one of front and rear wheel 115, can realize the rotation of wheel 115 coordinated drive assemblies 120 by a driven wheel 125.Yet, when needs drive front and rear wheel 115 simultaneously, two driven wheels 125 may be set in toy car 400.Except driven wheel 125, driven unit 120 also comprises a machinery or an electric rotating power source, and has a gear train, is used for the revolving force of power source is passed to driven wheel 125, controls the rotating speed (rpm) and the torque of revolving force simultaneously.

In the toy car 400 of the 4th embodiment, at the top surface of body 110 two secondary road wheels 130 and 130 ' are installed rotatably, they are operated together by a driven gear 135 coordinated drive assemblies 120.In this case, secondary road wheel 130 and 130 ' must partly be given prominence to the top surface of body 110, so that contact with the part that gets on the right track of track 140 to be same as with the mode of the contacted main road wheel 115 of lower railway part of track 140, and without any interference.Driven gear 135 is fixed in the first secondary road wheel 130 coaxially in the side-walls of selected wheel 130.

On the periphery of each secondary road wheel 130 and 130 ', form a permanent magnet with predetermined equal thickness.In this case, permanent magnet and must form the magnetic force that can support toy car 400 gross weights substantially in the form of a ring when the secondary road wheel 130 of toy car 400 usefulness and 130 ' is mobile along the part that gets on the right track of track 140.Simultaneously, main road wheel 115 can have this permanent magnet ring, perhaps, also can be made by nonmagnetic substance fully and without any magnet ring.

In the accompanying drawings, label 130 ' the expression second secondary road wheel, it has a permanent magnet ring, but different with the first secondary road wheel 130 be that it does not have driven gear 135.This second secondary road wheel 130 ' is used to guide toy car 400 stably to move on the part that gets on the right track of track 140.Certainly, can remove this second secondary road wheel 130 ' on the toy car 400 as free pulley.In addition, the second secondary road wheel 130 ' can have a driven gear 135, is used for operating together by driven gear 135 coordinated drive assemblies 120.When toy car 400 only has a secondary road wheel 130, preferably this road wheel 130 is arranged on the center of gravity place of toy car 400, move to realize the stable of toy car 400.

In toy car 400, there is a transmission device to be meshed with driving and driven

gear

125 and 135, be connected to each other thereby will drive with driven

gear

125 and 135, make to drive and driven gear co-operating each other.In a preferred embodiment, this transmission device comprises an idler gear 128, and it is rotatably mounted in body 110, and is meshed with two

gears

125 and 135 and they are interconnected, so that major and

minor road wheel

115 and 130 can equidirectionally rotate.When needs drive the first and second secondary road wheels 130 and 130 ' simultaneously, for these two secondary road wheels 130 and 130 ' provide two idler gears 128.In this case, these two idler gears 128 can be meshed with two driven wheels 125, maybe can the co-operating each other by an endless belt.

In the present invention, preferably make the diameter of the diameter of secondary road wheel 130 and 130 ', so that make toy car 400 have required excellent appearance less than main road wheel 115.When secondary road wheel 130 and 130 ' has than minor diameter like this, need recently suitably control the rotating speed (rpm) of secondary road wheel 130 and 130 ' by the control driven gear 135 and the gear of driven wheel 125.Therefore, the speed of toy car 400 under situation about moving with secondary road wheel 130 and 130 ' can be controlled to be and equal or be different from speed under situation about moving with main road wheel 115.Because idler gear 128 can not influence the gear ratio of driven gear 135 and driven wheel 125, thereby it can freely design to a certain extent as required.

Fig. 9 is the view that presentation graphs 8 toy cars 400 move continuously along upper and lower rail portion in the part of track.As shown in the figure, toy car 400 comprises that along one the two-orbit 140 of upper and lower rail portion moves.In this two-orbit 140, lower railway part 140 is horizontal components, and it comprises a magnetic part 140a and a nonmagnetic portion 140b.The part that gets on the right track 140 has a pair of bending magnetic part 140c.In this track 140, the nonmagnetic portion 140b of upper and lower rail portion relatively is arranged on the outer surface of two rail portion.

Along in the moving process of this track 140, toy car 400 partly moves along the lower railway of track 140 earlier in a conventional manner at toy car 400.When toy car 400 arrives nonmagnetic portion 140b on the lower railway part fully, the secondary road wheel 130 and 130 ' of toy car 400 is close to the part that gets on the right track, thereby toy car 400 is subjected to magnetic force hoisting and is attached to the part that gets on the right track with its

secondary road wheel

130 and 130 '.In this case,, drive and driven

gear

125 and 135 all clockwise rotates, thereby toy car 400 is in that secondary road wheel 130 and 130 ' moves to travelling backwards when partly advancing along getting on the right track with it as the clearest illustrating among Fig. 9.When toy car 400 arrived the nonmagnetic portion 140b of the part that gets on the right track fully, toy car 400 dropped on the lower railway part because of gravity, and partly moves forward along lower railway.Therefore, toy car 400 driven wheel 125 along a direction effectively during the rotation in Fig. 9 direction shown in the arrow move continuously along track 140.

In the process that moves along track 140, because toy car 400 partly rises to the part that gets on the right track because of magnetic force from lower railway, and because of gravity drops on the lower railway part from the part that gets on the right track, thereby main road wheel 115 can be without any the permanent magnet ring.In addition, also can make the lower railway part with nonmagnetic substance fully, and remove the magnetic part 140a in the lower railway part.

Above-mentioned track 140 has a simple structure and realizes the reserved area of track 140, thereby can keep this zone for the car 400 that plays with toys.This also can allow the user of toy car 400 need not repeatedly assemble or dismantle track 140, thereby the member of track 140 not too can be impaired easily or lose.

Figure 10 is the view of a part of structure of toy car 400 of a modification of expression fourth embodiment of the invention.Figure 11 a and 11b are respectively the structure of the walking mode converting means in expression Figure 10 toy car 400 and the view of operation.

The toy car of Figure 10 has a transmission device, and this transmission device is used as the part of walking mode converting means, and comprises that one is installed on the support 150 of body 110.Transmission device also has the idler gear 138 that an idler gear 128 and that is installed on support 150 is installed on support 150 and meshes with idler gear 128.Above-mentioned support 150 has a triangular pieces, and two rotating shafts of idler gear 128 and idler gear 138 remain in the place, two angles of this triangular supports.A bar 150a is installed at place, surplus next angle in three angles of triangular supports 150.This bar 150 is one significantly to stretch out the handle of body 110, is used for changing when needed the position of support 150 with respect to the body 110 of toy car 400.

Shown in Figure 11 a and 11b, above-mentioned support 150 can move between first and second position.That is to say that support 150 directly mesh idler gear 128 and driven wheel 135 in the primary importance of its Figure 11 a, and idler gear 128 is directly meshed by direct 150 idler gear 138 and driven wheel 135 in the second place of its Figure 11 b.Therefore, by between these two positions, changing the position of support 150, can make operator scheme conversion between two kinds of patterns of secondary road wheel 130 and 130 ' as required.In this case, the position of support 150 changes the rotation direction change that can cause driven wheel 135 or secondary road wheel 130 and 130 '.

In other words, when support was in the primary importance of its Figure 11 a, the mode that toy car 400 can be same as main embodiment to the three embodiment moved repeatedly and continuously along a cyclic track.Yet the toy car 400 that support 150 is arranged at the second place of its Figure 11 b can change another part that its moving direction maybe can move to track from a part of track.In Figure 11 b, the position of idler gear 128, idler gear 138 and support 150 when label 128 ', 138 ' and 150 ' represents respectively that support 150 is in its primary importance.That is to say that the position 128 ', 138 ' and 150 ' of the idler gear 128 among Figure 11 b shown in the dotted line, idler gear 138 and support 150 equals them and use the position shown in the solid line in Figure 11 a.In toy car 400, the central shaft of bar 150a, idler gear 128 and idler gear 138 is by deep-slotted chip breaker 110a, the 110b and the movable maintenance of 110c that are formed on the body 110, so that can move under the guiding of deep-slotted chip breaker.

In order to realize bar 150a, idler gear 128 and idler gear 138 smooth and easy the moving under groove 110a, 110b and 110c guiding, groove 110a, 110b and 110c form has required length on the support moving direction.In addition, groove 110a, 110b and 110c hold the central shaft of bar 150a, idler gear 128 and idler gear 138 movably, so that they can be moved swimmingly as required.Yet,, in the groove 110a of bar 150a, can form a lock slots for a select location that makes support can be locked in body 110 reliably and not produce undesirable displacement.The position that this select location with support is locked in body 110 also can be realized by a biasing device that is installed in the groove 110a of bar 150a, such as a latch plate.The groove 110b of idler gear 128 forms with driven wheel 125 has identical radius of curvature, even thereby support 150 move between the two positions, also can make idler gear 128 all the time with driven wheel 125 engagements.

In the present invention, for example can come electric power drive rod 150a with a motor or magnetic valve.In this case, preferably control the operation of motor or magnetic valve by remote control thereof.

Figure 12 is that expression Figure 10 toy car moves or lower railway in this part partly moves to the view of the rail portion in another part of track repeatedly along upper and lower rail portion in a part of a track.

As shown in the figure, when support 150 is in its primary importance and idler gear 138 is separated with driven gear 135, toy car 400 moves repeatedly along the lower railway part 141 and the part that gets on the right track in a part of track 140, thereby realize that to be same as Fig. 8 and 9 described modes circulation is mobile in this part, shown in the arrow " X " of Figure 12.Yet, when the position of support 150 is changed to the second place and when idler gear 138 is meshed with driven gear 135 from primary importance, toy car 400 is not moving to travelling backwards, but toy car 400 magnetic attachment in get on the right track the part bending part 143 time move forward, thereby realize that the lower railway part 141 in the part of track 140 moves to the rail portion 142 of another part of described track 140, shown in the arrow " Y " of Figure 12.

For the above-mentioned part from track 140 that realizes toy car 400 to the moving of another part, two bendings must be connected a position between another rail portion 142 that rail portion 143 be arranged on the horizontal rail part 141 of first and second portion.In this case, connect rail portion 143 and must have a magnetic part.

In the present invention, can use simple rectilinear orbit, arc track or circular orbit to be used as track 140, and can not influence function of the present invention.

In addition, when the body of toy car 400 was made by moulding technology by transparent plastic, children can observe gear train naturally from body 110 outsides and work in coordination with the operation that move the position of the support 150 in the transparent bodies 110 in the car 400 that plays with toys.Therefore, can improve children's science elaborative faculty.

Industrial applicibility

As mentioned above, the invention provides a kind of toy car.Different with the traditional toy car that is designed on horizontal plane to move, toy car of the present invention has that fixed cover is located at permanent magnet ring on each wheel, V-shaped groove, crawler belt, float and water wheels by its bottom centre between front-wheel and trailing wheel.Therefore, toy car of the present invention can effectively and swimmingly move on curved metal track, vertical metallic walls, metal ladder and the water surface, thereby playing method is various.This finally can allow children when playing this toy car, also can obtain scientific knowledge naturally except the enthusiasm of developing them and observation.

This toy car also is designed to and can moves in a looping fashion in the predetermined portions of a simple track, and is designed to and can optionally moves between two or more parts of track on demand.Therefore, this toy car can make the interesting car that plays with toys of children, and allows children obtain scientific knowledge naturally, such as the knowledge of relevant magnet characteristic.

Though more than described a preferred embodiment of the present invention for illustrative purposes, but those skilled in the art are appreciated that under the situation of the scope and spirit that disclosed various modification, interpolation and replacement can be arranged in not breaking away from as appended claims.For example, except the toy car of the preferred embodiment, the present invention also can be advantageously used in remote-controlled toy vehicle.
